nikon D800 – problemes poses longues pixels morts<\/p>\n<\/div>\n

\/\/\/\/<\/h5>\n
de\u00a0David Keochkerian photographie<\/a><\/h5>\n

Je suis l'\u00a0\u00bbheureux\u00a0\u00bb propri\u00e9taire d’un nikon D800 depuis bient\u00f4t 1 an. Comme vous l’avez remarqu\u00e9 je suis un adepte de la pose longue et du digital blending (fusion de plusieurs expositions dans photoshop via des calques et masques). J’associe tr\u00e8s r\u00e9guli\u00e8rement 2 filtres ND (un big stopper + ND0.9) pour obtenir des poses de 2 \u00e0 3 minutes. Je n’active donc\u00a0pas l’option anti-bruit du boitier (ce qui doublerait les temps de pose: 2 minutes pour l’image et 2 minutes de traitement). Je n’ai jamais activ\u00e9 cette option avec mon d700 sans jamais rencontrer aucun probl\u00e8me.
\nMais avec le D800… aie aie aie… d\u00e8s les premi\u00e8res utilisation en pose longue j’ai observ\u00e9 des images totalement pollu\u00e9es de point blanc. j’ai d’abord pens\u00e9 \u00e0 du bruit, mais j’ai remarqu\u00e9 que le ph\u00e9nom\u00e8ne \u00e9tait superposable d’une image \u00e0 une autre, les points sont toujours au m\u00eame endroit!!!! donc impossible que \u00e7a soit du bruit!!!! Je contacte donc le sav nikon pour plus de renseignements et ils font ceux qui d\u00e9couvre ce probl\u00e8me, qui pour eux est isol\u00e9 et me demande d’activer l’option anti-bruit… et effectivement \u00e7a r\u00e8gle le probl\u00e8me, mais option qui est juste impossible \u00e0 utiliser si on fait du DRI ou de la photo de nuit!!!!! Pour eux c’est du bruit!!!!!<\/p>\n

Je laisse donc courir mais je poursuis tout de m\u00eame mes recherches… jusqu’\u00e0 ce que je tombe sur le blog d’un am\u00e9ricain qui d\u00e9crit exactement le m\u00eame probl\u00e8me et qui teste diff\u00e9rentes m\u00e9thodes pour le r\u00e9gler mais en vain et d\u00e9cide \u00e9galement de contacter le SAV nikon USA…. mais l\u00e0 il lui dise clairement que c’est un PROBLEME du capteur du D800 dans les conditions de pose longue qui entraine ce ph\u00e9nom\u00e8ne!!!!! en aucun cas du bruit!!!!! mais qu’effectivement l’option anti bruit peut r\u00e9gler le probl\u00e8me. J’ai donc recontact\u00e9 le SAV france mais il on continu\u00e9 \u00e0 faire la sourde en oreille en me r\u00e9affirment que c’est du bruit et me conseille de ramener mon boitier… MERCI NIKON
\nJe sais maintenant que je ne suis pas le seul \u00e0 rencontrer ce probl\u00e8me, et je veux simplement informer les gens que ce boitier n’est peut \u00eatre pas le meilleur pour la pose longue. Vous ne pouvez pas imaginer le temps que je perds pour nettoyer mes ciels!!!! je vous joins quelques capture d’\u00e9cran de crop \u00e0 100% et un lien vers une video o\u00f9 je nettois 1\/5 d’un ciel, la video dure 15 minutes… en gros pour un ciel il me faut 1 heure juste pour le nettoyer!!!!!! un enfer!!! \u00e7a rend fou!!!!!<\/p>\n

je vous joins \u00e9galement la r\u00e9ponse de Nikon USA ainsi que l’adresse du blog:http:\/\/scottreither.com\/blogwp\/2012\/07\/01\/nikon-d800-e-long-exposure-issues-problems-2\/<\/wbr><\/wbr><\/wbr><\/a><\/p>\n

\u00ab\u00a0Dear Steve,
\nThank you for your update.
\nI have analyzed the sample image provided and consulted it with other Pro Support agents. It seems that the effect you are seeing is natural for D800 sensor and long exposure times \u2013 unfortunately there is no other way of removing the white spots than keeping the Long Exposure Noise Reduction active. I agree that it may not be convenient due to doubled exposure time, however currently there is no other solution to this problem due to limitations of the sensor technology.
\nWe apologize for the inconvenience,
\nPlease do not hesitate to contact us again in case of any questions.
\nKind regards,\u00a0\u00bb<\/p>\n","protected":false},"excerpt":{"rendered":"
